Communication apparatus and control method therefor

摘要

Regarding an apparatus capable of transmitting data using a high-rate transmission channel having narrow directivity and a low-rate transmission channel having wide directivity, data is not correctly sent in some cases because a communication path for the high-rate transmission channel is easily interrupted. In contrast, it is not possible to realize sending of high-quality data using the low-rate transmission channel. The same data is simultaneously transmitted using the high-rate transmission channel and the low-rate transmission channel. The data that has been received using the high-rate transmission channel or the data that has been received using the low-rate transmission channel is selected in accordance with a state of reception using the high-rate transmission channel.

1. A communication apparatus comprising:
a first communication unit configured to receive predetermined data via a high-rate transmission channel having narrow directivity; a second communication unit configured to receive, via a low-rate transmission channel having wide directivity, compressed data that is obtained by compressing the predetermined data; and an output unit configured to, in a case where an error occurs in reception of the predetermined data, decompress the received compressed data and output decompressed data, and in a case where an error does not occur in reception of the predetermined data, output the received predetermined data without using the received compressed data.
